(No model'l) To 107mm i may mwer'n: 'cies of space and the particular arrangement Be it known that -I,WILLIAM TOWNSEND; a of the conveying-tubes may require in some citizen of the United States, residing at Ohamca'ses terminals having an upward discharge paign, in the county of OhampaignandState and also an upward transmission, and in other 5 of Illinois, have invented certain new and usecases terminals having a downward discharge ful Improvements in Terminals for Pneuand alsoadownwar'd transmission.

termed a ,universal terminal-V-th'atis, a arrangement. These terminals are generally terminal the individualpart's or e lements of made up from metal castings (usually brass) which are capable of being assembled in a and have to be of considerable thickness and large Variety of forms to suit the, requireweight towithstand the shock and strain to 25 ments of different stations at which terminals which they are subjected by the propelling are placed. air-current and'the rapidly-moving carriers,

In the practical installation of pneumatic andwhere these castings have to be made in store-service and similar pneumatic despatch' a large variety of forms and proportions to systems in large buildings the exigencies of suit various forms and types of terminals 30 space, the widely-varying arrangements of the expense involved in the preparation of counters, shelving, aisles, wrappers stalls, the necessary Working drawings, the con &c., and numerous otherconsideration's re-. struction of patterns and other prerequisites quire often within a singleplant or system a l of their manufacture, is a very considerable large variety in the arrangement of the conitem in the total cost of installing a system.

35 veying-tubes and the receiving and despatch- I have set forth these considerations with ing terminals, particularly at the salesmens some particularity in orderthe more clearly ends of theline. ,Where the cashiers or main to emphasize the salient purpose or object of operatingstation is located in the basement,as my present invention, which is to provide a is usually the case, the receiving and despatchterminal for pneumatic store-service and 40 ing terminals'at the salesmens ends will usu other pneumatic-despatch systems which, as

ally be of the type known as the upward-dishereinabove stated, shall be in the nature of charge terminal, W here such cashiers staauniversal terminal-that is, a terminal'built tion is located on thetop floor of a building, the up out of certain component parts or elements salesmens terminals will ordinarily be of the which-are capable of being assembled and 45 kind known as the down ward-discharge terconnected together in a large variety of ways minal. Where the cashiers station is located in order to produce out of these same elements 5 on an intermediate floor, some of the salesor component parts a large variety of termimens terminals will be of the former and nals,whichat the pres'enttimeandinthepressome of the latter type. Again, the exigen- I cut-state of the art, so far as I am aware, re-

quire a special construction, involving special.

' metal ring or short sleeve in the nature of an internal ferrule, which is my preferred means for efiecting the union of certain of the parts.

Fig. 6 is a perspective in elevation of a hop-a per or upper member ofa chute used in connection with one of the forms of terminal. Figs. 7 to 17, inclusive, are views in elevation of various forms and types of terminals which are constructed by the union in difierent'ways of some or all of the elemental parts shown in Figs. 1 to 4, inclusive; and Fig. 18 is a general diagrammatic view of the interior of a store or other building, showing a typical pneumatic store-service system therein in which are embodied and combined in cooperative relation the various forms and types of terminals specifically shown in Figs.

, Similar letters and numerals of reference refer to similar parts throughout the several views.

The usual terminal at a salesmans station in a, pneumatic store-service system comprises abox orcasing havingsuitable guidesto direct the passage of carriers therethrough and in communication with two tubes through which a continuous air-current is maintained by a. suitableair exhauster or blower connected.

therewith, thecarrier being transmitted from the salesmans terminal to the cashiers station t-hro ughone of these tubes, usually termed the. sending-tube, and returned from the cashiersstation to the salesm-ans terminal through the other, commonly known as. the return-tube. In order to prevent inte'rruption of the air current flowing through I the tubes, bothtthe opening through which a carrier is. discharged and that through which it is.v transmitted. in asalesmans terminal are commonly guarded by a door or flap normally held closed, by gravity or spring action or by thesnction within the tubes, or by both, while atJthe cashiers end of the line the discharging-aperture is of course guarded bysuch a flap; but. the sending-aperture,being the pointatwhich the suction in the system begins, isin exhaustsystems left open.

In; carrying out my invention I have devisedfour specially formed, proportioned,and constructed parts or elements, as shown: in

Figs. 1 1304, inclusive, by the various unions or combinations of which I am able to secure the large. variety of terminalsabove referred to. The; first of these pa-rts(shown in Fig. l

and; designated as a whole by A) com-prisesa quadrant-shaped casting interiorly divided suasto-form'a curved guide afor the passage therethrough in either directionof a carrier and a short stub-section a for the return passage of the propelling-current. Communication between the parts a and (t is regulated and controlled by an arc-shaped sliding valve at, whose path of movement is along the curved line formed by the intersection of the parts a and a This valve may be actuated and set in any desired position to cut off the current more or less by a rack-and-pinion mechanism a a the latter being actuated by a thumb-nut a Figs. 8, 12, and 15, on the end of the pinion-shat t M. The ends Ct a? of the curved guide a, which are in planes at right angles to each other, are rounded and smoothed to receive clamping-rings B and D, respectively, Figs. 2 and 4, as hereinafter explained.

Referring next to Fig. 2, this view shows the second essential element of my device, which consists of an arc-shaped elbow casting B of suflicient internal diameter to permit of the easy passage therethrough of a carrier, and having its two open ends b and b in Dlanes at right angles to each other, as shown. On theinner curve of the elbow andextending approximately from one end to the other is formed an air by-pass B the function of which will be explained later. The end I) has aclamping-ring B, While the end I) is adapted in some forms of the invention to receive-the clamping-ring D, Fig. 4, and in others to be entered by a straight section of conveyingtube, as will be hereinafter explained.

Fig. 3 shows in detail the third essential part or element of my device. This comprises what I term a branched casting 0, formed of a short straight tube-sectionc and a slightlylonger curved branch section 0', com municating laterally with the section 0. The com munication of these sections a and c forthcpassage of carriers therethrough iscontro'lled by a switch 0, pivotally secured at 0 and adapted to hang loosely in some forms-of" the invention and to be fixedly secured in position across either section cor c in others by means-of'a set-screw 0 The three open ends c c and c of the casting C are all indifferenti but parallel, planes, and each of these ends is adapted in the various formsof the invention to receive the clam ping-rim g D and closed position against the ring D by means This deviceof a coil-spring 01 as shown. (shown-in Fig. 4) is=in the Various formsof my invention, illustrated in Figs. 7 to-l7', in'cl 'usive, adapted to be applied to all the other three'pa'rts- A, B, and 0, according to the-requ-ircmentsof each individual term-i'nahall as hereinafter fully explained.

Referring now to Figs. 7 to 17, inclusive,I have therein shown a few of the numerous types of terminals now in practical use in pneumatic store-service and other systems whichmaybeobtainedbycombinationofsome or all of the parts or elements of my present invention, said parts requiring no alteration in form, proportions, or structure whatever and being merely assembled and, connected together, preferably, by means of the short sleeve E, Fig. 5, or by a similar but longer section of tubing or by the split rings Band D. The particular means employed for connecting the parts is not, however, of the essome of the invention.

Fig. 7 shows the usual downwardly-discharging cashiers terminal. This as constructed by my invention is composed of the parts A, B, and D, connected together in the relation shown by the split rings B and D. The section of conveying tube 9', through which the carrier arrives from the salesmans station,enters the elbow-casting B at its end b and g is the exhaust-tube leading to the ex- 2 5 haust main or blower, whereby the current is maintained in the system, the direction of movement of the current being indicated by arrows in all the views.

Fig. 8 shows an upwardly-discharging cash 0 iers terminal. This comprises the same ele- -ments (A, B, and D) as Fig. 7, but differently united and arranged. The parts A and B. are connected together, as in Fig, 7 but the part B is turned down relatively to the part 5 A through a half-circle and forms the dis-.

charging-section of the device,the flap D being secured to its lower end, In this form of terminal and in all other forms in which'the part B is the section through which the car- 0 rier is finally discharged, as inFigs. 9, 10,1

12, 13, and 15, the by-pass B performs the function of preventing compression of the air.

in advance of the carrier and suction of the propelling-current in its rear to such an ex-v 5o minals as those shown in Figs. 7, 11, 14,16,

and 17, for the reason that the propelling-current in passing from section a to section a of the quadrant follows the carrier down nearly to the point of its discharge. Thetubee from the salesmans station joins the terminal at.

the end a of the quadrant A, and e is the tubeleading to the exhaust.

In Fig. 9 is shown a salesmans terminalin which the carriers are both received and trans- 6'0 mitted at the level of the counter. This ter-.

minal is made up from all the parts A B C D and the sleeve or ferrule E, the flap D closing both the discharging and transmitting ends of this and all the other salesmens terminals shown.

This terminal is like that above described in connection with Fig. 8 with the transmitter added, the part G'being joined at its end 0 to the part A by the internal sleeve E and being connected at its lower end 0 to the tube m, leading to the cashiers station. The switch 0 may either hang loosely or be set in the dotted-line position, Fig. 3. The tube 1, by which the carrier returns from the cashiers station, is connected to the part A at its end a", as shown, and the discharging and transmitting flaps D are secured by the split rings D to the ends 11 and c of the parts B and C, respectively.

The terminal shown in Fig. 10, also a salesmans terminaL-is similar in all respects to that last described, except that the carriers are not received .and transmitted at the same level, they being transmitted at the level of the counter, but returned with the sale-check and any change to the elevated stall of the parcel-wrapper, usually above and j ust in rear of the counter. Vided for by simply connecting the parts A and C by a straight section of conveying-tube E of the required length instead of by the short ferrule E and otherwise connecting the terminal to the sending and return tubes '21 and j, respectively, exactly as in Fig. 9.

A terminal having a downward discharge and an upward transmission is shown in Fig. 11. elements A, B, O, and D connected together, as shown, the parts A and 0 being united by the sleeve E. The elbow B connects the end a of the quadrant-casting A with the returntubefin a manner similar to that shown in Fig. 7, the carrier being discharged past the flap D, guarding the end a of the quadrant.

The sending-tube e joins the branch 0 of the part 0 at its upper end 0', and the carrier to.

the position indicated by dottedlines in Fig.

3 to permit the carrier to pass upward through the branch 0. i

Fig. 12 illustrates a modification of the-terminal shown in Fig. 9, showing how the same parts A, B, O, and D may be combined to accommodate a parallel arrangement of sending and return tubes 9 and h, respectively,

in a planeat right angles to, instead of parallel and coincident with, the plane of the discharging-carriers travel. In this terminal the parts are assembled as hereinabove described in connection with Fig. 9, except that the part C is joined tothe quadrant A by its branch 0 instead of by its straight section 0, the carrier to be transmitted to the cashiers station being introduced through the upper end c of the straight section a.

The combination and arrangement of the parts A, B, G, and D to secure a terminal having an upward discharge and an upward transmission are shown in Fig. 13.

the. return-tube it, as described in connection with Figs. 9, 10, and 12, the lower ordischarging end of theelbow B being guarded by a This terminal employs all four of the Here the j parts A and Bare .united and connected to This arrangement is proflap D and the part 0 being connected by sleeve E to the quadrant A by its branch .0, as in Fig; 12.' This terminal, it will be observed, is substantially like that shown in Fig. 12, with the sending-tube l and the flap D reversed as to their connection with the straight section c'of the part 0, so as to provide an upward instead of a downward transmission.

In Figs.14 and 15 I haveshown downwardly and upwardly discharging terminals, respectively, which are adapted for use in systems employing what is known in the art as a shifting current. An example of such a system is shown in the patent to Edmond A. Fordyce, No. 570,163, dated October 27, 1896. In such system-s a constant propelling current is not maintained through all of the salesmens terminals, but the current may be shifted, as it is called, at the cashiers desk, so as to be'scnt through any desired terminal, the others meanwhile being idle or dead, or so as to bring some outlying sta tion which has not an independent circuit connection with the cashiers station into communication therewith through some other salesmans station. Referring first to Fig. 14, this terminalis seen to be similar to that shown in Fig. 11 in that it has a downward discharge and an upward transmission; but in this case neither the sending or return tubes n and 1', respectively, are in direct connection with the cashiers station, but only indirectly through another salesmans station 1,6,.a's will be seen by reference to Fig. 18, to be explained hereinafter. Provision is made, however, for sending a through carrier from the cashiers desk directly through this station (without discharge) to a station 16 beyond bymeansof a return-tube q, connectingthe cashiers desk with the lower end ofthis terminal.

In its make-up this terminal comprises the parts A, B, and 0, arranged as in Fig. 11, except that the part C is joined to the quadrant A by its curved branch 0 instead of by its straight section 0, and another part .0 is superimposed upon the first-mentioned part .0, the two being united by a sleevev E at their corresponding ends 0 and through the curved'branch c of this latter part 0 the :local carrier to be transmitted isintroduced, while the through carriers pass this terminal by way of the alined straight sectionsof the castings O O. In this case the switch 0 in the first-mentioned orlower part 0 is fixed across the branch 0, while the switch in the latter or upper part C is allowed to swing loosely upon its pivotrto accommodate the passage of both-the local and the; through carriers. nThe terminal shown in Fig. 15, like that in Fig. 14, employs two superimposed parts G C to accommodate the,

passagelof both local and through .carriers, but'in thiscaseoflocal carrier is received di- .ectfrom thecashiers desk througha return- 1 lie-sand is discharged through the elbow B while it is transmittedito.the cash through terminal 9 by a tube .1 (which is a 'station15 without discharge by way of tubes 12 and o and the al-ined straight sections 0 c of the castings O O. L

Fig. 16 shows a salesmans terminal-having a downward discharge and a downward trans mission. This terminal employs the parts A, B,-and D assembled, as shown, in the cashiers terminal, Fig. 7, but has combined therewith a sender or transmitter in the form of the casting O, interposed between the quadrant A and the sending-tube p, as shown.

Fig. 17 shows an elevated discharge terminal sometimes employed at the cashiers station and connected to the endof a horizontall y-arranged sending-tube i. To make this terminal, the quadrant A, provided with the flap D, only is required; but'in order to insure the safe deli very of the carrier on the cashiers desk or table a hopper F, terminating in a curved chute F, is employed to receive the carrier on its discharge and guide it to its destination on the cashiers desk or table,

The various forms and types of terminals hereinabove described by no means exhaust the possibilities of my invention, but have been shown and described simply to adequately illustrate its practically universal character. In order to show one way in which I these various terminals might be coopera= tively united and combined in a single system, reference is had to Fig. 18, which will now be briefly described. The View is in the nature of a diagram, showing a vertical section of a store or other building having four stories and a basement. In the lower righthand corner of the basement is the exhaustfan or blower G, connected on its suction side with the exhaust-main H, locatedbeneath-the floor of the cashiers or operators desk I. The terminals shown in this figure I have for the sake of convenience and easy reference designated by numerals corresponding to the numerals of the several figures of the drawings in'which these terminals are shown in detail. In'the basement is shown theterminalll, directly connected to the cashiers terminal 8 by sending tube'e and'return-tube On the second floor, to the left, is shown the terminal12, directly connected to terminal 7 at the cashiers desk by sending-tube g and return-tube h. On thes'ame floor, to the right,

appears the terminal 10, directly connected to terminal 17 atthe cashiers desk by sending-tube i and return-tube'j. .On the third floor, to the left, is terminal 13, which is connected directly to the cashiers desk by areturn-tube 7c and indirectly connected thereto sending-tube relatively to terminal 13 and .a return -,t ube relativelytoterminal 9) and bya. sending-tube m. It will'th-usjbe seen gh terminal. 9, while'a carrier to be ,that a'carrier tobe sent from terminal 13; to the-cashiers station has to besent'by way of e -1 ICC returned from thecashiers station to terminal 9 has to be returned by way of and through terminal 13. On the same floor, in the middle, is shown terminal 14, which is indirectly connected to the cashiers desk through sendingtube n, terminal 15, sending-tube 0, terminal 16, and sending-tube 19, and also through return-tube q, terminal 14, return-tube 'n, terminal l5, return-tube 0, terminal 16, and'return-tube r. rier to be sent from terminal l4to the cashiers station has to be sent through terminal 15 (without discharge) and through terminal 16, (with discharge,) while a carrier to be returned from the cashiers station to terminal 14 has to be returned through terminals 14 and 15 (without discharge) and through terminal 16, (with discharge,) or else by way of returntube 5 and terminals 15 and 16, discharging at both stations. In this connection it will be noted that the tubes 02 and, 0 are sending-tubes relatively to a carrier to be 'despatched from terminal 14 and returntubes relatively to a carrier to be received there. On this same floor, third, to the right, is shown a terminal 16, which is directly connected' with the cashiers desk by a sendingdischarge,) and sending-tube 19.

tube p and also by return-tubes 0, n, and q, running through terminals 15 and 14 (without discharge) and forming, in effect, a single continuous return-tube, and also indirectly by return-tubes 0 and s and terminal 15, (with discharge.) On the top floor, fourth, at the left, is terminal 9, which communicates directly with the cashiers desk through sending-tubem and indirectlytherewith through return-tube 7t, terminal 13,

(with discharge,) and return-tube 1. At the right on this floor is the terminal 15, which communicates with the cashiers desk directly through return-tube s and: indirectly also through sending-tube 0, terminal 16, (with *In connection with terminalsl4, 15, and 16 and the two return-tubes q and s it is noted that in practice the'ends of the latter tubes at the cashiers station will be controlled by valves like those shown in the patent to Edmond A. Fordyce, above referred to, whereby when either valve is opened the other will automatically be closed, and thus the aircurrent will be passing through only one of the tubes q and s at a time. Thus by alternately opening and closing these valves the current may be shifted back and forth between tubes q and s to control the passage of local and through carriers between stations 14, 15, and 16 and the cashiers station, as de: sired. I

I have described my invention hereinabove as primarily designed for use in pneumatic store-service systems; but it will readily be understood that it might with equal advantage be employed in any pneumatic-despatch system wherein carriers, large or small, are transmitted by air suction or pressure from place to place, regardless of distance and of It will thus be seen that a car the nature of the matter carried by such car riers. The device hereinabove described, therefore, is not limited to use in connection with pneumatic store-service apparatus, but its application broadly and generally to any form or type of pneumatic-despatch system willbe withinfthe purview and spirit of my invention.
